Now there have been twelve incarnations of the time-traveling Doctor (discounting the War Doctor), one for every hour on the clock. You can use this desktop wallpaper series to keep track of time with the Doctor.

Head over to the Doctor Who subreddit for variant versions of this wallpaper and advice on how to get it to sync up with the clock on your computer. (And, if you're a registered reddit user, give stevensydan a little karma while you're at it.)

This is actually the second clever
Doctor Who rotating wallpaper series we've seen this week, the first being a series of wonderfully creepy Weeping Angel wallpapers.
